A Brian Wilson homecoming remains a longshot, but not necessarily an impossibility.

The beloved former Giants closer is expected to begin showcasing his arm for teams within the next few weeks, and general manager Brian Sabean's people have asked Wilson's representative to include them in the process.

Whether Wilson wants the Giants is a big question. By all accounts, the closer from the 2010 World Series title team was steamed that the Giants declined to tender him a contract after the 2012 season.

By rule, the Giants had to offer Wilson at least $6.9 million to keep him. They were unwilling to do so, not knowing what kind of pitcher he would be after a second Tommy John surgery.

Wilson became a free agent. Rather than sign a minor-league deal with one team to continue his rehab, Wilson chose to stay off the market while he rebuilt arm strength, then try out for teams when he looked ready to jump into major-league games.

Wilson underwent the operation in April 2012, more than 15 months ago. Pitchers ordinarily return from a first Tommy John surgery after one year if there are no complications.

A photo on Instragram seems to show Wilson throwing off the mound at USF on Friday. He also has trained in Los Angeles and Hawaii.

Vogelsong throws: Ryan Vogelsong threw 33 pitches off the AT&T Park mound, facing hitters for the first time since he broke his hand and declaring he felt good, although he was not happy with they way he threw some pitches.

"I came out healthy and was able to work on some stuff mechanically," he said. "It went pretty much like I wanted it to go."

Vogelsong threw to Gregor Blanco and coaches Roberto Kelly and Shawon Dunston. He admitted being a little "jumpy." He threw all of his pitches and did not allow any hits.

Kelly and Dunston won moral victories. Each made contact on some pitches, with Dunston muttering as he walked away, "They told me to swing. I haven't played in 11 years."

If Vogelsong feels OK on Sunday, he will pitch in his first game Tuesday in the Arizona rookie league.
